---------------------------------
Summary: The FederationInterceptor#launchUAM Added retry logic.
Key: YARN-11509
URL: https://issues.apache.org/jira/browse/YARN-11509
Project: Hadoop YARN
Issue Type: Improvement
Components: amrmproxy
Affects Versions: 3.4.0
Reporter: Shilun Fan
Assignee: Shilun Fan
There is a "todo" in the
FederationInterceptor#registerAndAllocateWithNewSubClusters method. According
to the "todo" description, the request needs to be retried to other
subclusters, but changing the parameter requests in
registerAndAllocateWithNewSubClusters is not a good operation. It is better to
add retry logic here.
We don't need to worry about losing requests because when the request cannot be
satisfied, the AM of the task will continue to apply, and these requests will
be properly transferred to other clusters for execution.
